Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed July 15, 1920. Serial No. 396,555.

To @ZZ fui/tom t may concern.'

Be it known that I, SPADY S. KOYAMA, a citizen of the United States ofAmerica, residing at Molson, in the county oi' Okanogan and State ofiVashin ton, have invented certain new and useful Fmprovements in Ships7Chairs, oi which the following is a speciication.

The primary object of the invention is the provision of a chairespecially designed for use upon shipboard whereby the seat isautomatically maintained in normal position for use and is capable oflateral oscillations at the will of the occupant.

A further object of the invention is the provision of a seat possessinggreat strength and taking up but little room although capable of use asboth a standard and a rocking chair giving ease and comfort to theoccupant.

A still further object of the invention is to provide a chair having aswiveled seat mounted for universal tilting movements and automaticallymaintained in its normal position for use, adjustable resilient return Ymeans being also provided.

With these general objects in view, the invention consists in the novelcombination and arrangement oit' parts hereinafter more fully describedin connection with the accompanying drawing and in which like referenceVcharacters designate corresponding parts throughout the several views.

In the drawing,

Figure 1 is an elevational view of the chair, Y

Fig. 2 is a central vertical sectional view through the seat and thesupporting means, and

Fig. 3 is a horizontal transverse sectional view taken upon line III-IIIof Fig. 2.

My invention being in the nature of a chair provides an elevated seat ofany desired form such as the seat 10 having a back 11 and side arms 12of the usualchair construction. A tubular standard 13 is mounted bymeans of a bottom flange 14 upon the floor or deck 15, suitable securingmeans such as 16 being employed.

A substantially heini-spherical socket 17 upon the top of the standard13 has a cup 18 iitted therein with a nipple portion 19 threaded intothe axle bore 20 of the standard 13. A journaling ball 21 is positionedin the cup 18 with a socket 22 mounted thereon, said socket 22 beingsimilar to the socket 17 and positioned opposite thereto, while the seat10 is secured by bolts 23 upon said upper socket 22. Y

n opening 24 diametrically through the ball 21 has a return spring 25extending therethrough and downwardly into the bore 20, the upper end ofthe spring being anchored as at 26 centrally through the socket 22 withthe lower end of the spring secured to an adjustable rod 27. The rod 27projects throughV a perforation 28 in a shoulder 29 adjacent the lowerend of the bore 2O while a nut 30 upon said rod 27 below the shoulder 29may be adjusted before the standard is secured to the floor forregulating the tension 0i. the spring 25. A plurality of springs 31 areconnected between the adjacent faces 32 and 33 of the sockets 17 and 22respectively for assisting the sprin 25 Vin maintaining the seat 10 1nits norma position and for returning the seat after being oscillated orpartially turned rotarily. The upper end 34: of the bore 2O is iared orenlarged for accommodating the spring 25 during the oscillations of theseat 1() relatively of the standard 13, it being understood that thesocket 22 is mounted for universal movement upon the ball 21 which isalso capable of slight movement within the cup 18.

A strong and serviceable chair is provided in which the occupant mayfind comfort in tilting laterally in any direction desired as well asturning swivelly to a'slight extent and while the form of the inventionherein set-forth is believed preferable, it will be understood thatminor changes may be made therein without departing from the spirit andscope of the invention.

at is claimed as new is:

1. A ships chair comprising a standard having a socket portion, a seatmember positioned thereabove with a socket portion 0pposite the socketof the standard, an antifriction ball within said sockets, theantiriction member and standard having axial openings in normalalinement with each other and a return spring for the seat adjustablysecured to the seat and standard members within said bores.

2.
